ok so i just got my technician license a couple months ago and ive been reading through part 97 trying to figure out exactly what im allowed to do. its honestly pretty confusing. like i get that i have HF privileges on 10m above a certain frequency and obviously VHF/UHF stuff but the part thats throwing me off is the stuff about third party communications and what counts as business communications.

my brother wants me to relay a message to someone at a hamfest about picking up some equipment he wants to buy. is that allowed? it feels like it might be crossing into business use territory but i genuinely dont know where the line is. and also does it matter if money changes hands or just the intent? i tried googling this and got like 5 different answers

yeah the third party traffic rules trip up a lot of new hams. so the short version is you cant use amateur radio to conduct actual business transactions, like taking orders, negotiating prices, that kind of thing. what your describing with the hamfest message is kind of a gray area honestly but most people would say just passing along "hey meet me at booth 12" is fine. where it gets iffy is if your actually helping someone make a purchase happen over the air. the FCC hasnt really drawn a super bright line there and most enforcement actions are about way more obvious stuff like using your license for a commercial enterprise. the key language in part 97 is about pecuniary interest, meaning you personally shouldnt be getting paid for the communication. your brother buying gear isnt paying you to relay a message so your probably fine but i wouldnt make a habit of brokering deals over 2m or whatever

I went through the same confusion when I was studying for my ticket. The way my Elmer explained it to me was basically — if you couldn't say it on a CB radio without it feeling weird and commercial, you probably shouldn't say it on ham either. That's a rough heuristic but it helped me internalize it. The actual rule in 97.113 lists out prohibited transmissions and business communications is definitely one of them but the FCC tends to care about patterns of behavior more than a one-off message about picking up a radio at a hamfest. Also worth knowing the ARRL has a pretty decent plain-English breakdown of part 97 on their site, way easier to read than the actual CFR.
